Graco InvisiPac GS35 Low Profile Four Module Applicator


Product Highlights

Graco InvisiPac GS35 Low Profile Four Module Applicator Overview

The Graco InvisiPac GS35 low profile, four module hot melt applicator is to be used in conjunction with the HM25 or HM50 tankless bulk hot melt systems to dispense char and plug free. This applicator was designed with a low profile to fit into tighter applications spaces.


Engineered for optimal control and with high speed and high temperature applications in mind.

Module Spring

The GS35 applicator module comes with a factory set spring that works across all pneumatic and fluid pressure ranges which means there is no need for fine adjustments.

GS35 Module Filter

This module filter was engineered to product the ball and seat from char and debris creating a clog free system. 

The Manifold

The Manifold on the GS35 applicator traps residual char or debris which is then removed when the filter is changed. The manifold filter is placed in a heated zone which means no cold spots so you have consistent dispensing.

Finally, the manifold can be brought up to heat in 10 minutes

* Both the InvisiPac GS35 and GM100 Plug-Free applicator have 2 different RTD options:
  1)  Pt 100(385) is a Platinum 100 ohm RTD. 
  2) Ni 120 is a Nickel 120 ohm RTD.

The name plate on the applicator will list which one to pick on the delivery system. If you pick an incorrect selection, the applicator may not heat properly or it may be damaged. Remember to specify the type of RTD in use on the Display Module.
